| 摘 要： | 大塘铅锌矿位于黔东铅锌成矿带中段,区域性施洞口断裂北西侧,矿体及矿化体呈似层状、脉状和透镜状赋存于下寒武统清虚洞组及中寒武统石冷水组地层中,含矿岩系为角砾状白云岩,矿石矿物主要为闪锌矿、方铅矿及少量黄铁矿,脉石矿物主要为白云石及少量方解石。矿石结构以粒状结构和假象结构为主,矿石构造主要为浸染状、细脉状和角砾状构造。该类型铅锌矿矿床有一定的规模,找矿标志明显。黔东铅锌成矿带中段内有铅锌矿点和铅锌地球化学异常区多处,通过了解该类型铅锌矿床地质特征和找矿标志,可望找到更多、更大的铅锌矿。

| Abstract: | Datang lead-zinc deposit is located in middle Qiandong lead-zinc metallization zone,the north-west side of regional Shidongkou fault.The ore body appeared as layered,vein and transparent,occurred in the stratum of Qingxudong formation,Lower Cambrian and Shilengshui formation,Middle Cambrian.The ore bearing rock series are brecciform dolomite,the mineral of the ore are sphalerite,gelenite and less pyrite,and the gangue mineral mainly are dolomite and less calcite.The ore structure mainly is grain structure and illusion structure,the ore structure mainly are disseminated,veinlet and brecciform.This kind of lead-zinc deposit has a bigger scale,the exploration target is abvious.There are many lead-zinc ore points and lead-zinc geochemical abnormality in the middle Qiandong lead-zinc metallization zone.By learning the geologic character and exploration target of this kind of lead-zinc deposit,it’s hopeful to find more and bigger lead-zinc deposit. |
